St. Catherine Laboure (1806-1876)
Catherine was a mystic who had a vision of St. Vincent de Paul; he told her that God wanted her to work with the sick. She later had a vision of Our Lady who described to her what is now known as the Miraculous Medal.

Reflections from the Saints

Every day He humbles Himself just as He did when from from His heavenly throne into the Virgin's womb; every day He comes to us and lets us see Him in lowliness, when He descends from the bosom of the Father into the hands of the priest at the altar.
– St. Francis of Assisi
